Hydraulic pressure system of rice transplanter with stepless adjustment of planting distance

Abstract

The invention relates to a hydraulic pressure system of a rice transplanter with an automatic differential locking function. The hydraulic pressure system comprises an oil tank, an oil pump, a plurality of electromagnetic valves and a plurality of motors, and further comprises a front wheel drive oil way, a rear wheel drive oil way and a transplanting oil way, wherein the front wheel drive oil way is connected with two front wheel drive motors; a synchronous valve is arranged between the two front wheel drive motors; the rear wheel drive oil way is connected with two rear wheel drive motors; another synchronous valve is also arranged between the two rear wheel drive motors; two output ends of each synchronous valve are both connected with an on-off valve; the transplanting oil way is connected with a transplanting motor; and a control circuit of each on-off valve is connected with an angle sensor arranged at a steering gear. The hydraulic pressure system is simple in structure, light in weight, convenient to array, low in failure rate and low in maintenance cost, and is a hydraulic pressure system of a full hydraulic rice transplanter laying the foundation for multi-functional development from the rice transplanter.

Description

[0001] technical field [0002] The invention relates to a rice transplanter, in particular to a driving system of the rice transplanter. [0003] Background technique [0004] The rice transplanter is one of the most widely used equipment in agricultural production, which greatly reduces the labor intensity of food production, especially rice production. Existing rice transplanters use mechanical transmission without exception, and this transmission method is highly praised for its transmission accuracy and mature technology. However, its complicated transmission mechanism restricts the multifunctional development of the rice transplanter, and also increases its maintenance cost. [0005] Contents of the invention [0006] The present invention mainly solves the technical problems of complex transmission mechanism and troublesome layout of the rice transplanter existing in the prior art, which restricts its multifunctional development, and meanwhile has technical probl...
